Technical details and manufacturing context for Electrode array

Definition

An electrode array is a critical component of an ionization chamber array, consisting of multiple precisely positioned electrodes that generate controlled electric fields to guide ionized particles. Within the ionization chamber system, it facilitates the collection and measurement of ion currents produced by radiation interactions, enabling accurate detection and analysis of ionizing radiation across multiple detection zones. The array typically comprises electrodes made of stainless steel (e.g., 316L per ASTM A240) or copper, with gold-plated contacts for reliable electrical connections. The number of electrodes ranges from 16 to 64, with an electrode pitch of 1.0 to 5.0 mm, determining the spatial resolution of the electric field. Insulation materials such as PTFE (per ASTM D4894) provide high dielectric strength and thermal stability. The operating voltage ranges from 100 to 1000 V DC, with higher voltages increasing ionization but posing a risk of breakdown. Insulation resistance is at least 100 MΩ (per IEC 60243-1) to ensure minimal leakage current. Capacitance ranges from 10 to 100 pF, affecting signal response time. The array operates within a temperature range of -40 to 85 °C. Ingress protection is rated IP54 to IP65 (per IEC 60529), protecting against dust and water jets. The weight ranges from 0.5 to 2.0 kg, and the footprint from 100×100 to 200×200 mm, fitting various chamber geometries. These parameters are reference ranges; model-specific values and standards must be verified with the legal manufacturer or supplier.

Working Principle

The electrode array operates by applying specific voltage potentials to individual electrodes, creating electric field gradients that attract and collect ion pairs generated when radiation interacts with the chamber's fill gas. The collected ion currents are then measured and analyzed to determine radiation characteristics such as type, energy, and intensity.

Frequently Asked Questions

What is the typical number of electrodes in an electrode array?

The number of electrodes ranges from 16 to 64, which determines the spatial resolution of the electric field. The exact count depends on the specific model and application.

What materials are used for the electrodes?

Electrodes are typically made of stainless steel (e.g., 316L per ASTM A240) or copper, with gold-plated contacts. The material choice affects corrosion resistance and electrical performance.

What is the operating voltage range?

The operating voltage ranges from 100 to 1000 V DC. Higher voltages increase ionization but may risk breakdown, so the appropriate voltage must be selected based on the application.

What are the environmental limits for the electrode array?

The array operates within a temperature range of -40 to 85 °C. It has an ingress protection rating of IP54 to IP65, protecting against dust and water jets.
